Reaktionsschritte
A solution of 3-bromo-4-fluorobenzonitrile (9.33 mmol) and cyclopropylamine (7.90 g, 136 mmol) in methanol (60 mL) was heated to 60° C. for 20 hours and concentrated. The concentrate was purified by flash column chromatography with 96:4 hexane/ethyl acetate to provide 2.63 g of the desired product. MS (ESI(+)) m/z 239 (M+H)+;
